Answer 1

@Wolken Software Ltd - When issuing a request with application permissions, a user must be specified in the members collection.

POST https://graph.microsoft.com/v1.0/teams
Content-Type: application/json

{
   "template@odata.bind":"https://graph.microsoft.com/v1.0/teamsTemplates('standard')",
   "displayName":"My Sample Team",
   "description":"My Sample Team’s Description",
   "members":[
      {
         "@odata.type":"#microsoft.graph.aadUserConversationMember",
         "roles":[
            "owner"
         ],
         "user@odata.bind":"https://graph.microsoft.com/v1.0/users('0040b377-61d8-43db-94f5-81374122dc7e')"
      }
   ]
}

If you are using the unattended client credentials flow to obtain an access token, then you must specify the user in the member collection.

Hi @Wolken Software Ltd

Make sure the target user has an O365 license, which is required to create a team.

Hope this helps.
